CLEVELAND - ABC News obtained new information about the captivity of the three women held for 10 years on Cleveland's west side.
Cleveland City Councilman Brian Cummins told ABC News that he was told by investigators that Amanda Berry's 6-year-old daughter was born in a small inflatable swimming pool during captivity.
Cummins said that inside the home on Seymour Avenue Michelle Knight, Amanda Berry and Gina DeJesus were kept in locked separate rooms and had to slide things in and out through holes cut open in the doors, ABC reported.
He expects additional details on the captivity and investigation to be released during a Wednesday afternoon news conference at 5 p.m.
A senior Cleveland police official told ABC News that the girls were originally kept in the basement until their spirits were broken, then they were allowed in other parts of the home.
Charges against Ariel, Onil and Pedro Castro are expected to be announced during the news conference.
ABC said the evidence suggests Ariel was the leader and primary perpetrator of the alleged abductions and assaults. Officials also have DNA from Berry's child to show he fathered the girl through an alleged rape.
The information from interviews with Knight, Berry and DeJesus were turned over to Cleveland police and prosecutors.
ABC said that investigators are also looking to see if there are any connections to the disappearance of another Cleveland woman, Ashley Summers, who went missing in 2007.
